Implementation of European regulations

ELES as the transmission system operator of the electric power network is in accordance with the legislation obliged to notify the public about the procedures of adoption and implementation of European regulations in the field of electric power transmission.

EU regulations overview

The Regulation establishing a network code on requirement for grid connection of generators (NC RfG) entered into force on 17 May 2016. The provisions of NC RfG set out detailed rules relating to the connection of, principally, new power generating installations to national electricity networks.

Regulation establishing a Network Code on Demand Connection (DCC)

The Regulation establishing a network code on demand connection (DCC) entered into force on 7 September 2016. The provisions of DCC set out detailed rules relating to the connection of, principally, new demand facilities to national electricity networks.

Regulation establishing a network code on requirements for grid connection of high voltage direct current systems and direct current-connected power park modules (HVDC)

The Regulation establishing a network code on requirements for grid connection of high-voltage direct current system and direct current-connected power park modules (HVDC) entered into force on 28 September 2016. The provisions of HVDC set out detailed rules relating to the connection of, principally, new high-voltage direct current systems to national electricity networks.

The System Operation Guideline is one of the network codes/guidelines drafted under the Third Energy Package. In 2015, the European Commission, ACER and ENTSO-E agreed to merge the three operational network codes into a single System Operation Guideline during their preparatory work for Comitology. The new guideline is composed of the former network codes on Operational Planning and Scheduling (NC OPS), Operational Security (NC OS), and Load Frequency Control and Reserve (NC LFCR). On 1 December the European Commission published the version of the Regulation establishing a guideline on electricity transmission system operation that was sent to electricity cross-border committee. The first meeting of the electricity cross-border committee on the System Operation Guideline is scheduled on 11 December 2015. The System Operation guideline will set down rules relating to the maintenance of the secure operation of the interconnected transmission system in real time. System operation guidline comes into force on 14 Septmeber 2017.

The draft Regulation establishing a network code on emergency and restoration received a positive vote in comitology on 24 October. The Emergency and Restoration network code will set down rules relating to the management of the electricity transmission system in the emergency, blackout and restoration states. The main objective of the relevant rules is to bring the system back to the normal state. The below is the provisional final version of the text, which will be shortly placed on the comitology register, with updates to numbering and referencing where required.

Regulation no. 2015/2022 establishing a guideline on capacity allocation and congestion management (hereinafter referred to as "the CACM") is the first among network codes which entered into force on 14 August 2015. The code lays down the allocation and stipulation of cross-border transmission capacities (CBTC) one day ahead and during the day, and it represents the key document in the efforts for the formation of a common European electric power market.

When speaking about the allocation of CBTC we speak about unifying the rules on allocation, the introduction of advanced allocation mechanisms that base on the so-called Market Coupling. ELES has been actively collaborating in these processes for a couple of years and the benefits of these processes are indisputable for market stakeholders and end consumers. The most important processes are:

more effective allocation of CBTC and better utilisation of transmission ways,

greater liquidity of local markets and the formation of a transparent price signal,

prevention of speculative trading (arbitration among markets),

reduction of costs of entering wholesale market (as a result of unification of rules) and increase of competition in the local market.

This is also the area where the largest step ahead has been made in the past few years.

Within the scope of preparation for implementing CACM GL, numerous activities are taking place in two areas: within the ENTSO-E and on regional levels, where various project groups have been established.

The Regulation establishing a guideline on forward capacity allocation (FCA) entered into force on 17 October 2016. The provisions of FCA establish a framework for the calculation and allocation of interconnection capacity, and for cross-border trading, in forward markets (i.e. timeframes longer than day-ahead).

Regulation establishing a guideline on electricity balancing (EB GL)

The draft Regulation establishing a guideline on electricity balancing (EB) received a positive vote in comitology on 16 March 2017. The Balancing guideline will set down rules on the operation of balancing markets, i.e. those markets that Transmission System Operators (TSOs) use to procure energy and capacity to keep the system in balance in real time. The objectives of the guideline include increasing the opportunities for cross-border trading and the efficiency of balancing markets. The below is the provisional final version of the text, which will be shortly placed on the comitology register, with updates to numbering and referencing where required.
